Summary

The purpose of this study is to evaluate the potential of \[18F\]-ML-10 to serve as an imaging tool for the early detection of response of brain metastases to radiation therapy. Such early detection may help early identification of responsive and non-responsive lesions. The experimental design of the present study aims to evaluate the potential of PET imaging with \[18F\]-ML-10 to address the currently unmet clinical need for very early (within one day)assessment of response to therapy. Currently, response assessment is available only after several weeks or months after completion of therapy, when tumor shrinkage can be detected by anatomical imaging (by MRI). Early detection of tumor response to treatment is now widely-recognized as a highly-desirable goal in oncology, and is respectively the target of intense research worldwide. In the future, the option to know early upon treatment administration, that the treated tumor is a non-responsive, may improve clinical management of patients with brain metastases of solid tumors.

Conditions

Interventions

DRUG

2-(5-fluoro-pentyl)-2-methyl-malonic-acid ([18F]-ML-10)

\[18F\]-ML-10 will be radiolabeled at the PET Radioactive Drug Production (RDP) facility at or in close proximity to each clinical site, and will be administered as an intravenous bolus injection (in 3-10 ml sterile saline solution, containing no more than 10% ethanol by volume). The dose concentration selected for \[18F\]-ML-10 will be 7 MBq/Kg or 0.19 mCi/Kg. The radioactivity dosage of \[18F\]-ML-10 administered at each PET/CT session will be at least 300 MBq (8.1 mCi) and not more than 500 MBq (13.5 mCi).

RADIATION

Stereotactic Radio-Surgery (SRS) therapy

SRS will be administered according to the standard of care using a radiation dose of 14-24 Gy to each lesion.

PROCEDURE

Positron Emission Tomography

Each patient will undergo 2 PET/CT sessions, each following intravenous administration of \[18F\]-ML-10, to assess tracer uptake by the brain metastases treated by SRS. The PET/CT scan will be directed to the brain and will include one bed position. The PET/CT sessions will be performed at baseline, i.e., before the radiation treatment, and on the day after, within 24h after SRS treatment.
